During the last two decades, several reports have indicated an increase in the number of type-2 diabetes among adolescents. Therefore, an assessment of adolescents' awareness of this disease deserves serious consideration. This study aims at designing a psychometric tool for assessing adolescents' awareness of type-2 diabetes.
In this methodological research, 770 students attending 10 middle schools (five girls "schools and five boys" schools) from Tehran participated in the study. The questionnaire was designed by examining the relevant literature and the existing questionnaires, as well as considering the research team's comments, and the initial pool of items with 57 questions was designed. Face validity, content validity, and construct validity were calculated to determine the validity of the instrument. Reliability was measured via internal consistency coefficient (ICC) and internal consistency reliability was measured with Cronbach Alpha. SPSS 16 was used for data analysis.
The questionnaire was initially designed with 57 items. Based on the results of CVR and CVI, five questions were removed. The average CVR and CVI were 0.75 and 0.82, respectively. Following exploratory factor analysis, the 30 questions in the questionnaire were categorized into five dimensions: public awareness, symptoms, behavioral risk factors, long-term effects, and medium-term effects. The internal reliability was calculated for the whole questionnaire-ICC = 0.87 with a Cronbach alpha coefficient of 0.80.
The resulting questionnaire on adolescents' awareness of type-2 diabetes, with 30 questions in five dimensions, can be employed by researchers for its high factor loading in factor analysis and its standard psychometric properties.
在过去二十年中，多项报告表明青少年2型糖尿病的数量有所增加。因此，评估青少年对这种疾病的认知值得认真考虑。本研究旨在设计一种心理测量工具，用于评估青少年对2型糖尿病的认知。
在这项方法学研究中，来自德黑兰10所中学（5所女子学校和5所男子学校）的770名学生参与了研究。通过查阅相关文献和现有问卷，并考虑研究团队的意见，设计了问卷，最初设计了包含57个问题的项目池。计算表面效度、内容效度和结构效度以确定该工具的效度。通过内部一致性系数（ICC）测量信度，并用Cronbach Alpha测量内部一致性信度。使用SPSS 16进行数据分析。
问卷最初设计有57个项目。根据CVR和CVI的结果，删除了5个问题。CVR和CVI的平均值分别为0.75和0.82。经过探索性因素分析，问卷中的30个问题被分为五个维度：公众认知、症状、行为危险因素、长期影响和中期影响。整个问卷的内部信度计算为——ICC = 0.87，Cronbach alpha系数为0.80。
所得的关于青少年对2型糖尿病认知的问卷，包含五个维度的30个问题，因其在因素分析中的高因素负荷和标准的心理测量特性，可供研究人员使用。
